To dream of a bog represents feelings of unbearable struggling to get through a problem. Unending difficulties. Feeling stuck in the middle of unpleasant situation that will never let you get away from it. Feeling forced into a "quagmire." A fear that there will always be another problem turning up to prevent you from making progress. Endless jealousy.
Example: A woman dreamed of falling into a bog. In waking life she had a broken arm misdiagnosed as a sprain, had to have the arm rebroken to correct improper healing, have surgery to correct the bone positioning, and then recover. He hospital stay felt endless with all the problems that kept coming up to achieve full healing.
